motion
The

is
located
in
the

part
men
mechanically
transmitted
from
the
remote
control
linkage
is
further
transmitted
to
the
inner
manual
lever
in
the
transmission
case
from
the
range
selector
lever
in
the
right
center
poc
tion
of
the
transmission
case
through
the
manual
shaft
The
inner
manual
lever
is
thereby
turned
A
pin
installed
on
the
bottom
of
the
inner
manual
lever
slides
the
manu
al
valve
spool
of
the
control
valve
and
thus
the
spool
is
appropriately
posi
lioned
opposing
to
each
select
position
The
parking
rod
pin
is
held
in
the
groove
on
the
top
of
the
inner
manual
plate
The
parking
rod
pin
operates
the
rod
at
p
range
and
operates
the
mechanical
lock
system
Moreover
the
above
described
manual
shaft
is
equipped
with
an
inhibitor
switch
A
rotor
inside
the
inhibitor
switch
rotates
in
response
to
each
range
When
the
range
is
selected
at
p
or
N
the
rotor
closes
the
starter
magnet
circuit
so
that
the
engine
can
be
started
When
the
range
is
selected
at
R
the
rotor
closes
the
back
up
lamp
circuit
and
the
back
up
lamp
lights
Vacuum
diaphragm
The
vacuum
diaphragm
is
installed
un
the
left
center
portion
of
the
transmission
case
The
internal
con
struction
of
the
vacuum
diaphragm
is
as
follows
A
rubber
diaphragm
forms
a
partition
in
the
center
The
engine
intake
manifold
negative
pressure
led
through
vacuum
tube
and
spring
force
are
applied
to
the
front
surface
of
the
rubber
diaphragm
and
atmospheric
pressure
is
applied
to
the
back
surface
A
difference
between
pressure
applied
to
the
front
and
back
surfaces
be
comes
a
vacuum
reaction
and
thus
the
throttle
valve
of
the
control
valve
inside
the
transmission
case
is
op
erated
When
accelerator

sufficiently
increased
the
manifold
negative
pressure
lowers
becomes
similar
to
the
atmospheric
pressure
and
the
vacuum
reaction
increases
since
the
flow
velocity
of
mixture
inside
the
intake
manifold
is
slow
Contrarily
when
the
engine
speed
increases
and
the
flow
velocity
of
the
mixture
increases
or
when
the
carbure
tor
is
closed
the
manifold
negative
pressure
increases
becomes
similar
to
vacuum
and
the
vacuum
reaction
reduces
Thus
a
signal
to
generate
hydraulic
pressure
completely
suited
to
the
engine
loading
at
the
control
valve
is
transmitted
from
the
vacuum
dia
phragm
and
most
suitable
speed
change
timing
and
line
pressure
are
obtained
so
that
the
most
proper
torque
capacity
is
obtained
against
the
transmitting
torque
Downshift
solenoid
The
downshift
solenoid
is
of
a
magnetic
type
installed
on
the
left
rear
portion
of
the
transmiSsion
case
When
a
driver
requires
accelerating
power
and
depresses
the
accelerator
pedal
down
to
the
stopper
a
kick
down
switch
located
in
the
middle
of
the
accelerator
link
is
depressed
by
a
push
rod
the
kick
down
switch
closes
cur
rent
flows

the
solenoid
the
sole
noid
push
rod
is
depressed
the
down

valve
of
the
control
valve
inside
the
transmission
case
is
depressed
and
the
speed
is
changed
forcedly
from
3rd
to
2nd
within
a
certain
vehi
cle
speed
limit
Note
As

of
the

the

of
the
switch
differs
